Out of interest for one of the pictures Rogs had on his page I went looking for an actual geographic location.
What I found was an interesting yearly festival, Burning Man Festival.
Burning Man, 29/8/11 - 5/9/11?
Once a year, tens of thousands of participants gather in Nevada's Black Rock Desert to create Black Rock City, dedicated to community, art, self-expression, and self-reliance. They depart one week later, having left no trace whatsoever.
Gabe Kierchheimer, a Photo Journalist has a fantasitc photo gallery of each yearly event in the link below.
and another excellent gallery for each year of the festival .
